Description

Treatment agent composition for hard surfaces

The present invention relates to a treatment agent composition for hard surfaces and a method for improving the wettability of hard surfaces.

The hydrophobic hard surfaces such as bathtubs have many vertical or inclined surfaces. In order to remove the stains in these areas, it is effective to use a sprayer to widely apply a cleaning agent containing anionic surfactants or amphoteric surfactants. However, if it is a vertical surface or an inclined surface of a hard surface such as a bathtub, the cleaning agent does not retain enough and drips in strips, so there is a defect that the effect of the cleaning agent cannot be fully exerted. On the other hand, there are also various methods for improving the adhesion and retention of the cleaning agent and reducing the contact angle by various methods of increasing the viscosity, thereby suppressing the cleaning agent dripping on the vertical surface and the inclined surface, so as to exert the cleaning effect. . Japanese Patent Laid-Open No. 2004-210808 discloses a method of using a polymer for increasing viscosity and a nonionic surfactant or solvent as a contact angle reducing agent. In addition, Japanese Patent Application Laid-Open No. 2018-536060 describes that a dishwashing agent containing short-chain alcohol can be sprayed.

However, Japanese Patent Laid-Open No. 2004-210808 has the problem that since a tackifier such as a polymer is required, it is not economical and cannot be sprayed with a sprayer. De-liquid and efficiently apply diffusion treatment agent. In addition, Japanese Patent Application Laid-Open No. 2018-536060 does not suggest that when a surfactant and a short-chain alcohol are in a specific ratio, the wet diffusivity can be improved when applied to a vertical plane.

The present invention provides a treatment agent composition for hard surfaces and a method for improving the wettability of hard surfaces using the same. The sprayability and dispensing stability of the sprayer are good.

The present invention relates to a treatment agent composition for hard surfaces, which contains (a) a hydrocarbon group having a carbon number of 6 to 12 and has an HLB (Hydrophile Lipophile Balance, hydrophilic/oil ratio) determined by the Griffin method of 2.5 to 9 to 9. The compound [hereinafter referred to as (a) component], 0.1 mass % or more and 10 mass % or less (b) surfactant (except for (a) component) [hereinafter referred to as (b) component], (c) water-soluble organic solvent [hereinafter referred to as (c) component] and water, and the mass ratio (a)/(b) of the content of component (a) to the content of component (b) is not less than 0.05 and not more than 0.43; The mass ratio (a)/(c) of the content to the content of component (c) is 0.1 or more and 1.4 or less, and the viscosity at 20°C is less than 50 mPa·s.

The present invention relates to a method for improving the wettability of a hard surface, which comprises bringing the above-mentioned hard surface treating agent composition into contact with the hard surface.

The present invention relates to an adhesivity and wet diffusivity improving agent of a composition containing a surfactant to a hard surface, comprising the component (a).

According to the present invention, it is possible to provide a hard surface treating agent composition for improving adhesion and wet diffusivity when spraying on a hard surface with a sprayer, and a method for improving wettability of a hard surface using the same. , and the sprayability and preparation stability of the sprayer are good. The hard surface treating agent composition of the present invention also exhibits high wettability to hydrophobic hard surfaces, so for example, when spraying on the vertical surface of the hydrophobic hard surface with a sprayer, it also has high adhesion and wet diffusivity without detachment. The residual amount of liquid and agent is increased. As a result, the cleaning power is also improved.

[Hard Surface Treatment Agent Composition] The reasons why the adhesiveness and wet diffusivity are improved when the hard surface treating agent composition of the present invention is sprayed on a hard surface by a sprayer, and the sprayability and preparation stability by a sprayer are good are uncertain, but are presumed as follows. The molecular mobility of the component (a) of the present invention, which has a hydrocarbon group with a specific carbon number and a specific HLB, is higher than that of the component (b) of the present invention, and the affinity with the hydrophobic surface is better than that of the component (b). When the hard surface is in contact with the treating agent composition, the component (a) is rapidly adsorbed on the interface, and a surface having affinity with the component (b) is formed on the hydrophobic surface. As a result, the hard surface treating agent of the present invention can be wetted and diffused on the hard surface, and the residual property of the treating agent can be improved. The effect can be achieved by using the (b) component and the (a) component in combination with the (c) component and the (a) component in a specific ratio, and even if it is a low viscosity that can be sprayed by a sprayer, it can be used. The treatment agent is wet and diffused on the hydrophobic hard surface, so that the treatment agent can remain. Furthermore, it is presumed that the preparation stability of the treatment agent can be made favorable. Moreover, (a) component of this invention is a hydrophobic compound, and it is very hard to dissolve in water. In order to stably dissolve this compound in the composition, it can be achieved by using together a surfactant as the component (b) and a water-soluble solvent as the component (c). However, if only the component (c) is blended, the effect of the present invention cannot be achieved, when the components (b) and (c) are insufficient, the components cannot be stably blended, and when there are too many components, the effect of the component (a) will be impaired. Therefore, the effect of this invention can be implement|achieved by making the mass ratio of (a) component, (b) component, and (c) component into a specific range.
